How do we know forgiveness is granted by God?

The assurance of forgiveness rests on the completed work of Christ who bore our sins. The Scriptures assure us that if we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness (1 John 1:9). This means that forgiveness is not based on our works or merit but solely on God's grace received through faith in Christ. When we repent and turn to God with our whole heart, as Israel did, we can be confident that He forgives us, fully and completely, knowing that it is Christ's righteousness that satisfies God’s demands.
